OSI Model

100

Handles character encoding, data encryption, and decryption.Example: SSL/TLS encryption for secure web browsing.

Layer 6

200

Manages communication sessions between devices. Handles session initiation, maintenance, and termination. Examples: Control protocols, tunneling protocols.

Session Layer (Layer 5)

300

• Responsible for end-to-end data delivery.
• Uses protocols like TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
• Assigns TCP/UDP port numbers.

Transport Layer (Layer 4)

400

• Handles routing and IP addressing.
• Uses IP addresses and subnet masks.
• Devices: Routers.

Network Layer (Layer 3)

500

• Manages communication between directly connected network devices.
• Uses MAC addresses (Media Access Control).
• Switches operate at this layer.
• Data units: Ethernet frames.
